What This Calculator Does
The Take-Home Pay Calculator turns your gross salary (or hourly wage) into the actual number that lands in your bank account every payday. It applies the four big subtractions: federal income tax, Social Security, Medicare, and state income tax — plus optional pre-tax 401(k) and health insurance. The result: per-paycheck take-home for any pay frequency, and a line-by-line breakdown showing exactly where every dollar of the gap between gross and take-home goes.
• Gross: $75,000
• − Federal income tax: $8,114 (after $15,000 standard deduction)
• − Social Security (6.2% × $75,000): $4,650
• − Medicare (1.45% × $75,000): $1,087.50
• − State tax: $0
• Take-home: $61,148.50 annually ($2,351.87 per bi-weekly paycheck)
Effective tax rate: 18.5% of gross.
The Four Big Deductions
1. Federal income tax
The biggest deduction for most filers. The IRS uses a progressive bracket system: the first chunk of income is taxed at 10%, the next chunk at 12%, then 22%, 24%, 32%, 35%, and 37% on the highest dollars. For 2025, the brackets (single filer) are 10% on $0–$11,925, 12% on $11,925–$48,475, 22% on $48,475–$103,350, 24% on $103,350–$197,300, 32% on $197,300–$250,525, 35% on $250,525–$626,350, and 37% above. Married Filing Jointly brackets are roughly double. The bracket math applies to your TAXABLE income, which is gross income minus your standard deduction ($15,000 single / $30,000 MFJ in 2025) minus pre-tax 401(k) and pre-tax health insurance.
2. Social Security (6.2%)
Funds the federal old-age, survivors, and disability insurance program. It's 6.2% of your wages, but ONLY up to the Social Security wage base — $176,100 in 2025. Wages above that aren't taxed (and don't count toward your future SS benefit, either). If you make $300,000, your SS tax is the same as someone making $176,100: $10,918.20. Your employer pays a matching 6.2% on top — self-employed pay both halves (12.4%, with the employer-equivalent half deductible).
3. Medicare (1.45% + 0.9% surtax)
Funds Medicare hospital insurance. It's 1.45% of ALL wages — no cap. So if you make $1 million, you pay $14,500 in regular Medicare tax. On top, the Additional Medicare Tax of 0.9% applies to wages above $200,000 (single / HoH) or $250,000 (MFJ). This surtax is the employee's responsibility only — employers don't match it. Self-employed pay 2.9% Medicare on net SE earnings (with the same 0.9% surtax thresholds).
4. State income tax
Varies dramatically. Nine states have no state income tax: Texas, Florida, Nevada, Tennessee, Washington, Wyoming, South Dakota, Alaska, New Hampshire. California's top marginal rate is 13.3%. New York and New Jersey top out around 10-11%. Most other states are in the 4-7% range. Plus cities: NYC adds ~3.8% on top, Philadelphia ~3.8%, Cleveland ~2.5%. This calculator uses a single flat-rate input as an approximation — accurate 50-state modeling requires a per-state engine that's outside the scope of a single tool.
Pre-Tax Deductions — The Tax Hack That Isn't a Hack
Pre-tax deductions reduce the income you're taxed on, which reduces your tax. The two big ones:
401(k) — Lowers federal income tax, NOT FICA
Money deferred into a traditional 401(k) (or 403(b), 457, TSP) is excluded from your federal income tax base. If you're in the 22% federal bracket and defer $10,000, you save $2,200 in federal income tax. BUT 401(k) contributions are still subject to Social Security and Medicare — so you still pay 7.65% FICA on the deferred amount. The 2025 401(k) limit is $23,500 ($31,000 if 50+, including the $7,500 catch-up). Roth 401(k) is the opposite: contributions are after-tax, but withdrawals in retirement are tax-free. This calculator models traditional (pre-tax) 401(k) only.
Health insurance premiums — Lowers both income tax AND FICA
If your employer's health plan is set up as a Section 125 cafeteria plan (almost all are), your share of premiums is deducted PRE-TAX. That means it doesn't count for federal income tax OR for FICA wages OR for state income tax (in most states). This is why employer-sponsored health insurance is structurally cheaper than buying the same coverage on the marketplace with after-tax dollars — you're skipping 7.65% FICA + your marginal income tax rate + state tax on every premium dollar. A $5,000 annual premium might cost you only $3,200 in after-tax terms.
Pay Frequencies — Same Annual, Different Cadence
Your pay frequency doesn't change your annual take-home — it just splits it differently:
- Weekly (52 checks): Smaller, more frequent. Common in trades, restaurants, retail.
- Bi-weekly (26 checks): Most common in the US for salaried W-2 employees. You get two "bonus" months a year with 3 paychecks (whichever month has 5 of your payday weekday).
- Semi-monthly (24 checks): Paid on the 1st and 15th, or 15th and last day. Always 2 checks per month — no "bonus" 3-check months. Slightly less common than bi-weekly.
- Monthly (12 checks): Rare in the US. More common in Europe and for executive comp.
The math: annual take-home ÷ check count = per-paycheck take-home. The calculator shows all four side by side so you can see what each frequency would look like.
Annual Salary vs Hourly Wage
For salaried employees, the annual is given (it's what's on your offer letter and W-2 box 1 plus pre-tax deductions). For hourly workers, the calculator does the conversion: hourly rate × hours per week × 52 weeks = annual gross. The default is 40 hours/week × 52 = 2,080 hours/year — the standard full-time assumption. If you regularly work overtime, use your average hours. If you work part-time, use your actual hours.
What's NOT in This Calculator
Tax credits — Child Tax Credit ($2,000/child under 17), Earned Income Tax Credit (up to $7,830 for low-income families with 3+ kids), Saver's Credit, education credits, Premium Tax Credit (ACA subsidies). These reduce your TAX OWED at filing time, not your paycheck withholding. If you qualify for $4,000 in credits, your refund at filing will be $4,000 higher than this calculator's take-home would suggest.
Other paycheck deductions — Roth 401(k), HSA contributions, FSA contributions, dependent care FSA, commuter benefits, group life insurance, disability insurance, union dues, garnishments, child support. Many of these have favorable tax treatment we don't model.
State tax brackets — modeled as a single flat rate instead of state-specific progressive brackets.
Local taxes — NYC, Philadelphia, San Francisco, and other cities add their own income tax. Not modeled.
SDI / SUI — State Disability Insurance and State Unemployment Insurance withholdings (California SDI is 1.1% up to $153k of wages; New York has its own). Not modeled.
AMT — Alternative Minimum Tax. Mostly doesn't trigger post-2017 reform but can for high earners with large state-tax deductions or ISO exercises.
NIIT — Net Investment Income Tax (3.8% on investment income above $200k single / $250k MFJ MAGI). Not modeled.
How to Use This in Real Life
Comparing job offers. A $120k offer in California isn't the same as a $120k offer in Texas. Plug both into this calculator with the appropriate state rate. The Texas take-home is about $7,000-$10,000 higher per year. Comparing offers in pre-tax dollars hides a real cost-of-tax difference.
Negotiating a raise. Your raise from $100k to $115k is NOT $15k more in your pocket — it's roughly $9,500 after federal and FICA (more if you have state tax). Knowing the after-tax delta helps you negotiate more realistically (and budget more realistically).
Deciding whether to max your 401(k). If you're considering boosting your 401(k) contribution from 5% to 10% of salary, run both scenarios through this calculator. The take-home drop is smaller than the contribution increase because the IRS is subsidizing the difference via lower federal tax.
Budgeting from after-tax income. Your monthly budget should be built on take-home, not gross. The 50/30/20 rule (50% needs, 30% wants, 20% savings) applies to take-home pay, not salary. Use the monthly take-home from this calculator as the input to the Budget Planner.
The Difference Between Withholding and Tax Owed
Your employer doesn't know your final tax liability — they estimate it using IRS withholding tables, your W-4 selections, and your pay frequency, projecting your annualized income. At year-end you file a return and reconcile. If too much was withheld, you get a refund. If too little, you owe.
This calculator estimates your ANNUAL tax liability based on the bracket math, not your withholding. For most W-2 employees with straightforward situations (single job, no side income, standard deduction, no credits), withholding tracks pretty close to actual tax owed. For people with side income, multiple jobs, or who recently got married/divorced, withholding can drift — file a new W-4 with your employer if you want to bring it closer in line.
Why the Math Is Worth Understanding
Most Americans don't know their take-home pay until they look at their first paycheck after starting a job — and even then, they don't know exactly which deduction is which line. Understanding the math gives you better negotiating leverage (knowing what raises are actually worth), better budget planning (knowing what you have to spend), better retirement planning (knowing what 401(k) contributions cost in real after-tax terms), and better decision-making on benefit elections (pre-tax health insurance vs marketplace, HSA contributions, etc.).
The big software providers (TurboTax, ADP, Gusto) all run essentially this same calculation behind the scenes. The math isn't a secret — it's just buried under interface complexity. Here it's the whole tool.
Educational Tool — Not Tax Advice
This calculator implements the standard federal income tax + FICA + flat-rate state tax math. For real tax filing, use IRS forms or licensed software (TurboTax, FreeTaxUSA, H&R Block, etc.). For complex situations — business ownership, multiple states, AMT exposure, large investment income, equity compensation — a CPA pays for themselves. For the actual amount on your paycheck, your employer's payroll system is the source of truth; ask HR to walk you through your stub if any line is unclear.
